Demand regulator

A demand regulator for a breathing apparatus comprising:

• a flow regulation mechanism for regulating a flow of breathing gas, the flow regulation mechanism having a closed configuration in which breathing gas flow is substantially prevented;
• a connection mechanism for releasably connecting the flow regulation mechanism to a breathing mask, the connection mechanism comprising a release actuator for releasing the connection mechanism;
• a latch configured to be activated to thereby releasably retain the flow regulation mechanism in the closed configuration;
• a first latch activation mechanism configured for manual actuation by a user to thereby activate the latch independently of the release actuator, so that a connection between the flow regulation mechanism and the breathing mask is maintained;
• and
• a second latch activation mechanism configured to be actuated by the release actuator of the connection mechanism to thereby activate the latch during release of the connection mechanism.
